The Pairing Switch and LED (pin 3 and 4) are located on the top of the Bluetooth Audio Interface. The

there are two pins on the connector which can be wired to an external pairing switch and LED. For
more details on LED status and switch functionality, reference Section 3.1.
The pairing switch pin input accepts a momentary ground input and the LED output pin provides a
